Analysis Summary:

The article's core claim about a nearly three-year papal election is plausible, but the provided sources do not directly verify this specific event. The sources touch on revolts and religious conflicts, but not papal elections. Therefore, the factual accuracy is mixed due to lack of direct verification. The bias is minimal, as the snippet is descriptive and does not appear to present a strong opinion.

Detailed Analysis:

• Claim:** The election of a new pope will soon begin. This is a general statement and cannot be verified or contradicted by the provided sources.
• Claim:** The four most recent conclaves lasted, on average, two days. This is a factual claim that could be verified with external sources, but is not covered by the provided sources.
• Claim:** But the longest ever went on for nearly three years. This is the central claim. None of the provided sources directly confirm or deny this. The sources discuss revolts (Verification Source #1, #2, #3, #5) and religious conflicts (Verification Source #4), but not specifically long papal elections.

Supporting Evidence/Contradictions:

• The provided sources do not offer direct support or contradiction for the claim about a nearly three-year papal election.
• Verification Source #1, #2, #3, and #5 discuss various revolts, but these are unrelated to papal elections.
• Verification Source #4 discusses the Investiture Controversy, a conflict between the papacy and the Holy Roman Emperor, but does not relate to the length of papal elections.
• Due to the lack of direct verification, internal knowledge suggests that some papal elections have indeed been lengthy, but this cannot be definitively confirmed by the provided sources.
